In Wal$-$Mart, a security guard notices a young man clutching his chest near the exit. In response, the security guard detains the young man and brings him to a room marked "employees only". In the room, security guards make the young man remove bandages near his chest to show them a recent scar from a surgery, and to prove he was not shoplifting.

After $45$ minutes, Wal$-$Mart determines that the young man did not shoplift from the store, and is free to leave. During this time, the door to the "employees only" room was left open.

If the young man wants to sue Wal$-$Mart for false imprisonment, will he win and why?

Yes, because security footage will prove that the young man did not shoplift

Yes, because he was detained without consent or freedom to leave

Yes, because the detention lasted $45$ minutes

No$,$ because Wal$-$Mart had left the door open, so the young man was 'free to leave at any time
